In another concept from Norman Foster and partners, a series of five hilltop towns would adorn Bulgaria's coastline and attract vacationers from far and wide. Visitors to the Black Sea Gardens would drive from inland highways and leave their cars in underground parking lots at the entrance to each village. From there, tourists and residents alike would move around the town using electric shuttle buses, communal bicycles, and the power of their own feet.

Each hill town would boast narrow streets to provide shady walkways and sunny balconies, and houses would be nestled into the hillside. At the water's edge, a marina would provide a natural gathering point and a connection to the sea.
